'7 Claims.

The present invention relates to an infants toilet seat, and particularly to a structure of this character which is readilydetachable to, or removable from, the conventional toilet seat.

, The principal feature of the invention resides in atoilet device which is secured in position on the usual adults toilet seat by'movement of the back portion of the device into raised position,

the seat portion being preferably secured to the V usual or conventional seat by. engagement with the opposite sides thereof, thereby accommodating itself to the various types of toilet seats. The objectsand further advantages of the invention will appear from the following detailed description taken in connection with the accompanying drawing in which:- I Fig. l is a side View in elevation of an infants toilet device embodying the invention.

Fig. 2 is an enlarged fragmentary elevation of the pivotal'connection between the back and the seat portions of the device. 7

Fig.3 is a vertical 'sectionalong the line 3-3 of Fig. l. I V Fig. 4 is a fragmentary vertical section along the line 4-4 of Fig. 1. 7

Like referencecharacters refer to like parts in the different figures. j 1

Referring to the drawing, thev device comprises a seat portion I of the usual form havin an opening 2 therein, and a back portion pivotally mounted adjacent theback of the seat portion and arranged to extend upwardly substantially at right angles to the seat'portion or, when in folded relation, adjacent and substantially parallel tothe seat portion. Arms 4 are pivotally mounted on the; back portion 3 on opposite sides thereof and project forwardly in parallel relation to the seat portion 1 to support the child on the seat. Each of said arms is supported at the forward end in spaced relation to the seat portion by a link 5, the-upper end of which is received in an opening-6 in the side of the arm for pivotal movement thereon. The lower end of the link projects into and is pivotally mounted in a horizontal opening l in the side of the seat portion.

The back portion 2 is resiliently supported in the raised position shown in Fig. l bya clip 8 secured to the side of the seat portion as by screws? and provided with a vertically arranged notch H which engages the link 5 when the latter is in the substantially vertical position shown.

The clip is resilient and permits folding of the.

device by a forward pressure on the back portion to move the device forwardly. said clip yielding to permit the link 5 to move out of the notch H therein, although supporting said back against accidental folding; or forward movement.

V The pivotal connection of the back portion are 7 the seat 'p'ortionis bestshown inFig. 2. Referring to: this figure, an angular lever 62 is secured V at one end .toeach lower corner of the back por:

tion as by screws {3 and the free end of .said le- 7 ver extends forwardly and is pivotally mounted on a screw l i in,the"side ofxthe seat portion'z. By this arrangement of the'lever, movement 'of the back portion rearwardly is limited by'engage ment of the'lower edge !5 of said. back portion with the upper surface of the seat portion, without the provision of additional stops, and said back portion is readily folded: forwardly about the pivotal screws I4." 1; r 3 7 As best shown in Fig. 3,,the under side of the seat portion! is provided with opposed depending hooks lt and H which are adapted to'engage opposite sides of the permanent or adults toilet seatl for securing the infants-seat thereto. Thesehooks, as will beapparent, engage theperrnanent'seat and secure; the infants toilet'seat against sliding movement thereon'fas' well as against removal f-romfsaid adults seat. 'The seg curing. action is aided'by rubber knobs 2i! on the under side of the seat-at opposite-endsthereoff which engage the upper surface of the adults seat.

Thedepending hooks l6 and I! which arepref- .erably rubber covered, as shown, areformed on the forward ends of'rods 2i pivotally mounted on the under side of the seat portion in brackets 22 secured to said seat portion. The rearward portions 23 of said rods beyond the brackets are bent to extend upwardly'and outwardly innot ches 24 providedin the seat portion forwardly ofthe pivotal. screws M. The outer end of each rod engages a slot 25 in an arm ZSpiVotally mounted at the end remote from'the slot on the screw 14 and beneath the lever l2.' Each arm 26 is pro vided with an outwardly projecting lug 21 for engagement with'the lower horizontal edge 28 of the lever l2 for movement of said arm by said lever as the back portion 2 is moved into the raised position shown, thereby elevating the ends 23 of the rod and procuring movement of the hooks l6 and Il'away from each other and into locking engagement with the adults seat. -Each arm 25 is" also provided with a second outwardly projecting lug 39 in a position to engage the upper edge 3| of the lever l2 as the back portion 2 is i infants seat. It will be noted that the lugs 21 and 30 are positioned so that the securing hooks are moved into operative engagement with the adults seat as the back portion 2 approaches the end of its movement into raised position, and similarly the securing hooks are withdrawn from operative engagement as the back portion 2 ap proaches the end of its movement into folded position. In this way the device is not immediately released from the adults seat by a slight forward movement of the back portion; in fact, the device cannot be removed from the adults seat until the back portion is moved into substantially parallel relation to the seat portion.

From the foregoing, it will be apparent that the infants seat is locked on the permanent adults seat by movement of the back portion into raised position, the locking occurring as the back approaches the end of its movement in this direction. The back portion is resiliently maintained in raised position to prevent accidental release of the securing members, which are released by folding movement of the back portioninto parallel relation to the seat portion, said securing members being released as the back portion approaches the end of its movement into folded position. Release of the infants seat, from the permanent seat is'thus impossible while a child is positioned on the seat, even though the back portion 3 be moved part of the distance into folded position.
